Recent research published in the journal Energies has unveiled a groundbreaking methodology for sizing Dynamic Wireless Power Transfer (DWPT) infrastructures on highways, which could significantly enhance the viability of electric vehicles (EVs) for long-distance travel. Led by Valerio Apicella from Movyon SpA—part of the Autostrade per l’Italia group—the study addresses one of the major barriers to electric vehicle adoption: range anxiety caused by limited battery capacity.
As global greenhouse gas emissions continue to rise, the transportation sector remains a significant contributor, particularly in Europe where road transport accounts for 72% of emissions from the transport sector. The research highlights the need for innovative solutions to transition from traditional internal combustion engine vehicles (ICEVs) to battery electric vehicles (BEVs). One promising approach is the implementation of DWPT systems, which allow vehicles to charge while in motion, reducing the need for frequent stops at charging stations.
Apicella’s team developed a traffic flow simulator that uses real data from Italian highways to determine the optimal number and length of DWPT segments required to support electric vehicle traffic without necessitating recharging stops. This tool serves as a decision support system for highway operators, making it easier to plan and implement charging infrastructure.
The study’s findings indicate that a well-structured DWPT system could cover significant stretches of highway, with the research conducted on Italy’s A1 highway showing that a combination of 1 km to 10 km charging segments could satisfy around 57% of vehicle journeys. This translates to a potential infrastructure of 138 charging plants over approximately 437 km of highway, with an energy demand estimated at 1.9 GWh per day.
Apicella emphasizes the importance of this research, stating, “The complexity of the layouts identified for a hypothetical DWPT infrastructure highlights the need for careful planning in both road and energy networks.” He also notes that DWPT should complement traditional charging stations rather than replace them, indicating a mixed approach to charging infrastructure will be essential for meeting future demands.
The implications of this research extend beyond environmental benefits. For commercial sectors, particularly those involved in transportation and electric vehicle manufacturing, this presents an opportunity to invest in and develop infrastructure that can support the growing market for EVs. With the increasing pressure on companies to reduce their carbon footprints, adopting such innovative technologies could not only enhance operational efficiency but also align with sustainability goals.
As the demand for electric mobility continues to rise, the findings from this study could pave the way for more extensive and efficient charging networks. The methodology could also be adapted to other highway networks, making it a versatile solution for various regions.
In summary, the study by Apicella and his team offers a promising pathway to overcoming the limitations of electric vehicle technology, potentially transforming highway travel and contributing to a more sustainable future. The research, published in Energies, underscores the urgent need for innovative solutions in the transportation sector to combat climate change while providing significant commercial opportunities.
